" I wnrra, or sen raancrsoo, CALIFORNIA almost impossible two or three feet of form is to be supported by to provide a telescoping REENFORCED CONCRETE FILE CONSTRUCTIGN Application filed Novemberl, 1927.

My invention relates to reenforced concrete pile constructions in which the piles are driven for the purpose of supporting a deck or platform of concrete or other material, the

elevation of which is fixed.

In driving piles it is impracticable and uneconomical to bring the top ends to any predetermined elevation above the bottom or above the water level. In many instances it to drive a pile within a predetermined elevation. It has been the practice, heretofore, to cut oi the piles after driving at the exact elevation required for placing the deck. In case of concrete piles, the cutting itself is not only expensive but in addition it delays the work so as to greatly increase the cost of pile driving.

Another disadvantage in the methods now used in pile driving, is that due to hidden obstructions in the bed in which they are driven, they cannot be properly centered. This being the'case it is almost impossible to predetermine any point at which a deck or platthe piles, before the piles are actually driven.

It is a well known fact that concrete piles exposed to sea water deteriorate very slowly, if at all, below the water level, and that the deterioration is most rapid in the length of the pile immediately above the water level which is exposed to the air and to the splashing of the water. It is evident that if the pile is protected in the belt immediately above the low water level, the life of the pile will be greatly prolonged.

In general it is the object of my invention cap or sleeve at the upper end of a driven pile which can be adjusted for height, so that the top of the cap or sleeve can be quickly and economically set to the exact elevation required for: supporting the deck or platform.

Another object of my invention is to provide a telescopically adjustable pile, the sections of which are provided with sufficient play or looseness with respect to each other, so as to allow the upper section which is to support the deck or platform to be centered on a predetermined line.

Another object of my, invention is to provide a telescopically adjustable pile, the up per deck supporting section of which, also serves as a sheath or'shield for protecting the concrete which is later to be poured into the upper section and which forms an integral part of the concrete deck.

The invention. possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description where I shall outline in full thatform of my invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown one form of reenforced concrete pile construction embodying my invention, but it is to Ice-understood that I do not limit myself to such .form since the invention as set forth in the claims may be embodied in a plurality of forms. I

Referring to the drawings:

Figure 1 is a vertical. section of my telescopically adjustable pile, the upper section of which has been shown as supporting a deck or platform.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. l and looking in the direction as indicated by the arrows.

Fig. 3 is a horizontal section taken on the line 8-3 of Fig. 1 and looking in the direction as indicated by the arrows.

My telescopi 'ustable pile comprises chosen so as to insure, that after being driven into the ground, its upper end will be sufii-' ciently below the predetermined level of the deck or platformto obviate any necessity of cutting off or trimming its upper end. Telescopically engaged over the upper end of the driven pile .4 is an adjustable hollow cap or sleeve 5 preferably formed of concrete by precasting. .After the upper end of the cap 5 has been'adjusted to its proper predeten mined height with respect to form which it is to support, the clamps 7 are adjusted under its lower end and are secured to the driven pile by means of bolts 3. Moulding forms 9 on which concrete decks or platforms are to be poured may then he supported the deck or plat- 9 on the upper end of the cap by meansof upper end of the driven 'a leg integral with thedeck.

clamps 12 secured to the upper end of the cap 5 by means of bolts 8. It will be noted that there is a space 13 between the driven pile 4 and its telescoped cap 5. The purpose of this space. 13, is to allow the upper end of the cap 5 to be centered with respect to any predetermined point relative to the deck. Afterthe cap 5 has been centeredand adjusted to the proper level,;the space 1 3 is sealed with a cement grout 10. The concrete deck can then be poured into the form 6-. 7 At the time that the deck is poured, the space 11 above the pile 4- is simultaneously poured with concrete therebyforming The length of the cap 5 is preferably chosen in hand." s e y HARRY E sQUIRE,

so that its lower end extends approximately'tothe water 7 7 level atrl'ow tide.

' It will thus be seen that by the'aboveconstruction I have v e readily adjusted to any predetermined elevationwithout the necessity of trimming or e cutting. The upper or supporting end of my a driven pile which j pile can be readily centered with respect to any predetermined point on the deck or platform to be supported and'the'upper section of taneously serves as a sheathing or protection for the concrete leg which is'moulded in the space 11.

I claim: p p I 1. The method of extending a driven pile to a' predetermined position which comprises positioning an extension on said pile, said ex 7 tension having a loose fit withrespect to said pile, supporting said'extension on said pile,

and adjusting said extension vertically and laterally to said predeterminedposition. V

3, That steprin providing a vertically and horizontally adjustable extension to a driven pile which comprisestelescoping' an extension over the top of said driven pile, positloning .a clamp on said pile to support said extension on said pile, andadjusting said extenr sion Vertically and horizontally we desired position. 7 .c

4. The method of extending a previously driven pile to a predetermined exact elevation for supporting a platform, which comprises positioning and vertically adjusting a suitabletel'esooping sleeve about the pile, and
